How to check the online payment of patent fees in China Patent Electronic Application Network?

If you have paid the fee and the national administrative department has accepted it, you will get the patent application number. At this time, you can use this application number to go to the patent examination information inquiry websites in China and many countries to inquire about the current relevant information of the patent you applied for, and you can also find your payment information and payable information in it.

It can be seen that you should have paid the application fee, publishing and printing fee and substantive examination fee at one time, so it can be seen that your patent should have just been applied and has not yet entered the actual examination stage, so the actual examination fee should be placed in the State Administration Bureau, and their system has not registered to pay the actual examination fee. After the preliminary examination is passed, the substantive examination fee in the payable information should be changed to paid information. Another reason is that the website of the National Knowledge Bureau will have a certain lag and will not be displayed so quickly.
